ABSTRACT:
A bulk conveyor is described, including an elongated belt with means for supporting the belt along its working flight. The working flight support includes a number of cradle members connected in spaced relation along opposed roller chains. The chains are trained about sprockets between end rolls that mount the conveyor belt. The chains and the sprockets rotatably mounting them to the frame permit simultaneous motion of the cradle support members with the belt along the working flight. They also hold the cradle members in proper transverse orientation to the belt length. The cradles are supported along tracks that bear the weight of the cradles and of the load carried on the working flight. Motion of the cradles along the working flight is simultaneous with the belt so there is little frictional sliding engagement between the contacting surfaces of the belt and cradle. The belt leaves contact with the cradles along its return flight and rides over spaced support rolls below the returning cradles. Wheels on the cradles may be selectively adjusted to maintain proper wheel alignment along the frame-mounted tracks in relation to the planes of the roller chains.
